Definitions

  • the invention relates to a transmission belt. power, usable in the automotive industry, in home appliances and many others industrial fields.
  • a belt of this type can be trapezoidal or with a striated internal surface and generally comprises a reinforcement of cables wound in more or less spaced turns from each other and drowned in rubber or in the elastomer of the belt, these cables used for the transmission of forces between a driving pulley and a or more driven pulleys.
  • the pulley rotation speeds can be relatively high and are often variable. It is frequently observed in practice that belt strands, i.e. parts of the belt between two pulleys or rollers, vibrate at certain pulley rotation speeds or on more or less wide ranges of rotational speeds, these vibrations can generate noise and cause premature wear of the belts and reduction of their service life.
  • the present invention aims to solve this problem in a simple and effective way.
  • It relates to a transmission belt of power which has a better behavior in vibration than the current belts and which also has a service life at least equal to or greater than that of current belts.
  • the invention makes it possible to combine the advantages presented by cables of different types while avoiding or by reducing their disadvantages.
  • the strap comprises two cables of different natures, whose turns are in a 1/1 alternation, a turn of a cable being placed between two turns of the other wired and vice versa.
  • the cable turns can be in a different alternation, where a group of turns adjacent to a cable is placed between two groups of turns of another cable and vice versa, the numbers of turns per group which may be identical or different for different cables.
  • This belt 10 which is intended by example to be mounted on a motor vehicle engine for the rotational drive of various organs such as a pump, an alternator, etc. striated type and includes on its internal surface a certain number of circumferential ridges 12 having a shape trapezoidal in cross section, the striations 12 being parallel to each other and extending over the entire length of the belt, and being intended to be engaged in grooves of corresponding shape pulleys on which this belt is mounted.
  • the belt 10 comprises at least one ply 14 of cables 16 which are embedded in rubber or elastomer constituting the belt 10, at short distance of the outer surface 18 of this belt, the cables 16 being spirally wound to form in the belt coils more or less close to each other, the number of turns included in the width of the belt being a function of the desired mechanical characteristics of this belt.
  • At least two are used different cables to form the turns of the sheet 14, and the turns of different cables are arranged alternately.
  • a turn of a cable 16a is located between two turns of another cable 16b and, conversely, a turn of cable 16b is located between two turns of cable 16a.
  • m turns of a 16a cable arranged between two groups of n consecutive turns of another cable 16b, m and n being integers greater than 1.
  • the numbers m and n are not too high.
  • the different cables intended to constitute the armature of a belt are selected according to their vibration damping and resistance properties dynamic fatigue.
  • the cords of polyester yarn allow to manufacture belts with good mechanical properties and good resistance to dynamic fatigue. Through against, these belts have little vibratory behavior satisfactory, especially when the belt strands between pulleys are relatively very short or relatively very long.
  • Aramid cords allow you to make belts with good vibratory behavior, but poor resistance to dynamic fatigue and therefore short service life.
  • Belts including alternating turns of polyester yarn and aramid yarn have by against good vibrational behavior, good resistance dynamic fatigue and a long service life.
  • the test results of these belts revealed excellent vibrational behavior and very good resistance to dynamic fatigue.
  • the belts according to the invention represent significant progress over the prior art, due to the fact that they benefit advantages of the different cables used to constitute their reinforcement without being subjected to inherent disadvantages of these cables.
